What is the .32 NAA ?


 

Background

At the 2002 NRA Convention in Reno, NV, the partnership of North American Arms (NAA) and Cor-Bon Ammunition introduced the .32NAA, a new cartridge and gun combination designed for the law enforcement (backup) and personal protection markets.  “As the only caliber to exceed 1000 feet per second [muzzle velocity] from a pocket pistol, we expect the .32NAA to attract some attention,” said Sandy Chisholm, NAA’s president.  When asked about production plans and availability, Chisholm responded that both firms had already begun production and shipments to distributors from both factories were scheduled for the first week of May 2002.

The .32NAA was built from the foundation of an ordinary .380ACP case, necked-down to house a .32 caliber bullet.  Behind the neck, all case dimensions and configurations, including the extractor groove, rimless case, cartridge diameter and bolt face engagement are identical to the .380ACP.  Cor-Bon determined that a headspace on the shoulder allowed a solid crimp on the bullet, reducing the possibility of the bullet pushing into the case from recoil and chambering.  After finalizing a case design which maximized case capacity of the cartridge as well as allowing sufficient case neck so that a bullet would be held securely, Cor-Bon spent several months testing a wide variety of bullets of different weights and configurations, finally settling upon a proprietary design from Hornady.  The platform for this new system is the .380ACP Guardian, appropriately bored and chambered for this cartridge – no other mechanical changes were found necessary.

  • Makarov.com and North American Arms began working on the Makarov conversion barrels for this hot little round, with some ground work done by North American Arms, in Feb of 2003 at the 2003 Shot Show in Orlando, Florida.

    The two completed Makarov pistols shown below were assembled by George Fisher, and included a custom built two tone 8rd Makarov with a stock length barrel, and a stock Russian IJ70-17AH (originally .380 ACP, Hi Cap) that only had the barrel changed out, and a new recoil spring installed.

    The original factory ammunition, for testing, was provided by Cor-Bon, by way of Ken Friel of North American Arms, and consisted of a 60 JHP at a quoted 1200 fps out of the cartridges original pistol, the North American Arms Guardian.

    Makarov Performance Overview

    First off, I gotta say, this setup performs much better than I could have hoped for. After a few rounds to figure out the proper recoil spring weight, both pistols worked flawlessly, feeding and ejecting without a hitch. Due to the limited ammo available for testing, the data is not as extensive as I would have liked (and it was a ball shooting it) but that will change when the next batch of ammo arrives, along with some handload data when the dies arrive.

    The recoil is not as stout as the Makarov in 9x18, more like a .380 ACP recoil, however the muzzle blast and flash were more along the lines of a tame CZ-52. Accuracy was good considering the limited amount of shooting we got to do today, with Karl turning in the best group with 5rds in a nice 3 1/2 inch group fired @ 7yds.

    Later testing turned up groups as small as 2 inches at 15yds (I think the barrel needed a few rounds to break in)

    The velocity champ was the Extreme Shock 60 gr "Fang Face" load, which clocked an outstanding 1817 fps from the extended length Makarov barrel.

    The Conversion Process, How hard is it ?

    Changing the barrel on the Makarov is a fairly simple and straight forward process. See the online website for more info on this process. There are a few changes that are made when installing the .32 NAA Conversion barrels, due to the smaller bore diameter. The removal process is the same, but the normal practice upon installing the new barrel is to use a threaded rod through the center of the barrel to pull the new barrel in place. There has been some discussion in the past if this practice would damage or mark the rifling. George Fisher of Makarov.com devised a way to use the standard barrel press to push the new barrel in place, without use of any tooling intruding into the chamber or rifling of the new barrel.

    The Barrel press is reversed and a spacer block is used between the rear of the barrel and the muzzle block, and the nuts tighten down evenly to push the new barrel in place. See Picture. This process can also be used with any caliber Makarov barrel. A standard socket can be used as the spacer, or one will be included with purchase of the .32 NAA barrels upon request. Once the new barrel is installed, the barrel pin hole must be drilled with a #31 drill bit (available below), and can be done with a standard hand drill.

    All other parts of the Makarov remain the same, including the extractor and Magazines.

    Handloading the .32 NAA:

    Reloading Dies

    Currently reloading dies for the .32 NAA are being custom made by Lee Precision, and can be ordered directly from them.

    Brass

    Once fired brass can be used for reloads of course, and is the best choice for the proper headstamp. The good news is that since the .32 NAA is just a necked down .380 ACP case, brass can be made by just lubing .380 ACP brass and running it through the .32 NAA sizing die. Use of new brass is recommended for this, unless you know the history of the used brass you have on hand.  We also offer New Production .32 NAA brass below.  This brass is annealed for proper case forming and longer life.  It has the .32 NAA headstamp.

    Bullet Selection

    Just about any bullet suitable for reloading the .32 ACP will work for the .32 NAA. These include the popular 60 grain Jacketed Hollow Points, the 71 grain FMJ, 76 grain FMJ, and various cast bullets in the same bullet weight range.
